` MANSFIELD, OHIO, A CORPORATION OF NEW JERSEY sPLIoER V ApplicationIfilad July 6,

My invention relates to splicers particularly for trolley wires.

'The Object ofmyinvention is to provide A an efficient holding devicefor the butted z'j'ends of the trolley wire leaving the under surfacefree for the smooth and uninterrupted'passage of the current collector.V

My invention resides in the new and novelconstruction, combination andrelation of 1'0 the parts hereinafter described and shown in theaccompanying drawings;

In the accompanying drawings: Fig. l is a side View in elevation andpar- Mtial section of my invention.` 'F Fig. 2 is'a section on the line2-2 of lg. i V F ig. 3 is a section on the line 2--2 showing the pin inholding relation with a trolley wire. l Y Fig; 4 is aview of the underside of a portion of the splicer'without the wire in V position.

' V`My invention is an improvement upon that w invention shown in Patent1,773,193 issued tomeAugust 19, 1930.

I have-found that it is desirable to pro- V: vide means for preventingthe insertion of the endpin into the wire to as great a depth Kas in thecase of the other pins in order to Vreduce the amount of distortion towhich the trolley wire is subjected to upon the pin being forcedtherein. V My invention comprises a body member v 41 with a plurality oftransverse openings 2 in which are positioned preferably steel pins 3land 4.V o

The pins are made With a sliding fit in the holes 2 and are providedwith a reduced p V end 5 and a tapered end 6. T Along the upper edge ofthe splicer -are projecting flanges 7 and 8 which are normally as' shownin Fig. 2, but after the pin has been 'forced into position by means ofMa' tool as shown in my patent above referred to the flange takes theformation shown in Fig. 3 and interlocks Vwith the tapered por- 'tion 6of the pin, 'thus preventing the pin backing out;

In order to maintain all the pins of the l Vsame length which isdesirable fromL the 1931. serial Na. 548,941.

manufacturers, and customers' standpoint, I

provide bosses 9 surrounding the end pins 4 and which bosses are raisedabove the surface 10 of the splicer and these bosses 9 act as a seatagainst Which the compressor tool referred to contacts, thus limitingthe amount of insertion of the pin into the Wire. The difi'erence towhich the pins 3 and 4 may be forced into the wire is represented by thedifference in the dotted lines at A.

This same result could of course be Secured by making the pins 4 shorterthan the pins 3, but this Would mean the manufacture of two lengths ofpins and the danger of the pins becoming ntermixed, but by the abovedescribed means the pins are all the salne and the depth to Vwhich thepins may be forced into the trolley wire 11 is controlled by lfiXedmeans upon the splicer. p V

It will be recognized of course that the pins 3 next to the pins 4 maybe arranged so as to force into the trolley wire a little greaterdistance than the pins 4 by surrounding the pins 3 with bosses of lessheight than the bosses 9, but not as far as the third pins from the end.

cel

Also the body may be tapered in height from a maximum at the end mumatthezinner pins.

The body is provided with a groove 12 along its lower edge to receivethe trolley pins to a miniwiresll and the lips'13 to prevent thedisplacement of the wire transversely. V

In order to take care of the metal of the trolley wire which is forcedout of it, slight pockets 14 are formed opposite the passages 2 thustformingmeans to receive the 'forced out metal and also forming aninterlock with the trolley wire to prevent in addition to the pinsthe'longltudinal displacement of thewire relative to the splicer. o

' It is desirable to have the trolley wire distorted as little aspossible adjacent the end of the splicer and therefore by my improvedsplicer I accomplish this result.

Having described my invention, I claim 1. A wire splicer lcomprising anelongated body member, an open grove along one edge' of the body toreceive wires from both ends and inwardly projecting meansto preventVthe wires being displaced transversely of the groove, a plurality 'ofmeans of uniform length slidably mounted in the body member 5 andmovable transversely of the aXis of the wires to interlock with thewiresto prevent the longituclinal movement of the wires in 'the groove, thesaid means being arranged insubstantiallyalinement with their aXes inualplane coinci'ding withthe aXis ofthey connected wires and meanssurrounding each extreme end means to limit the insertion of the saidend means into the wires to a less' amount than the intervening. means.
